Only one problem with this- a belief is not a matter of perspective and thought. A belief is formed based on knowledge and understanding of life. If you have little of both, then you end up with irrational, nonsensical beliefs, which lead to irresponsible behavior. And, that leads to irresponsibility of oneself, for not understanding life.
Reality exists freely of independent thought, desires, will, or wishes. Reality is all knowable.
Example: cure for cancer isn't real yet. Therefore it is not in reality. Yet, the second a cure is found- now it becomes part of reality, because it exists.
Reality at the point will change and a new reality will be maintained.
You form a belief on a 'god', for whatever reason- you can never believe in it 100% completely, because nature of man and woman says you can not back it up, because it's outside reality.
Even your inner-core(subconscious) won't believe in a 'god' 100%, because it knows it's not in your nature to believe anything other than something that is real can exist. It is hope that drives the band-wagon.
But, in the end- your belief is based on what knowledge you have and how well you understand what you know(wisdom). To form a belief in any other manner is irrational.
